"more samples" /sec translates to frequency bandwidth in digital audio.
96000 samples are 96000 samples even if you SRC a 48kHz signal to 96KHz.
Let me know what you find.
Thing is: Lets assume you do have a mic that "hears" up to 48Khz and you record at 96k. You import that to a 96k session and time-stretch that. Lets assume you have a perfect algo that won't hurt the frequency content.
Then you import it into a 48k session via SRC. By doing that you will lose any content above 20kHz again. So unless you stay at 96k you can not preserve the information contained in the 96kHz file so in the end you could have recorded and worked at 48k in the first place.
Where it does make sense for FX is to pitch down the 96k file to bring down the HF content into an area that you're able to hear. So you still have some high content compared to a recording recorded at 48k and pitched down by 2 octaves resulting in a sound with only 5kHz of maximum HF content.
